About Enzootic Bovine Leukosis (EBL)/Bovine Leukemia Virus (BLV)
Bovine leukemia virus (BLV) is a retrovirus that may cause lymphosarcoma in cattle. The virus resides in blood lymphocytes where circulating antibodies are unable to neutralize it. Therefore, once an animal is infected with BLV, it is infected for life.
BLV is economically significant to the producer because of premature culling or death as a result of lymphosarcoma. Another concern is the condemnation of carcasses at slaughter, which has a significant economic impact on the dairy and cattle industries. Losses from export restrictions are another economic concern of BLV infection. Countries that have bovine leukosis control programs require BLV-free certification prior to shipping cattle to their regions. Moreover, exporters of semen are under increasing pressure to ensure that their product is from a BLV-free animal in a BLV-free herd.
